Description

Shopping cart

Technical field

[0001] the present invention relates to a kind of shopping cart, it has equipped a token system and a retainer.

[0002] effect of this token system is until this shopping cart could be taken out from a gathering station after inserting one piece of token, and until just can fetch token after sending this shopping cart back to a gathering station.Until just can use this shopping cart after one piece of token inserted this token system again.

[0003] this retainer prevents from can using a shopping cart outside the zone of a restriction.

Background technology

[0004] multiple token system known in the state of the art.In some systems, many can be mutually nestable shopping carts couple together with lock and chain.In order to use this shopping cart, one piece of token must be inserted in the lock.Only have and just can discharge token after this shopping cart being packed into another shopping cart and again being connected to another shopping cart with chain.

[0005] in many token system, in order to disengage token, shopping cart also needs to be bolted on the gathering station with another chain and can disengage token.

[0006] the also known retainer that has several types in the prior art.These retainers are used for preventing from using shopping cart outside the permission zone of a restriction.These retainers comprise the device for detection of the adimission area, and are used for stoping the additional mechanical effect device that uses shopping cart.Some retainers are arranged, wherein by at least one roller shopping cart is prevented from.In other retainers, the turning to of shopping cart is restricted and makes it no longer can be along traveling priority.

Summary of the invention

[0007] the invention reside in the following fact: namely the element of the well known elements in the token system and retainer interacts, and this new interaction provides a kind of new combination with cooperative effect.

[0008] this token system has been used the element that is used for keeping and discharging this token, and this retainer has used and stops this roller or limit the element that it turns to.

Embodiment

[0009] element for maintenance and release token comprises a sensor, and whether it can detect the shopping cart that the element that is used for maintenance and release token has been installed thereon and be pushed among another shopping cart.

The element that [0010] then, should be used for maintenance and release token is enabled this retainer and is discharged token.

[0011] in order to use shopping cart, one piece of token must be inserted this and be used for keeping and discharging among the element of token.Then this retainer is deactivated.

[0012] enabling of this retainer prevented that this shopping cart from opening rolling unintentionally.

[0013] in a development of the present invention, the arrangement that provides makes degree that the function of this sensor is expanded for the one or more other condition that exists is responded to, and is only additionally satisfying other or during a plurality of condition, just can discharge token.

[0014] one of these other conditions can be positional informations, and this positional information is guaranteed to only have when this shopping cart is parked in an ad-hoc location and just can be discharged token.

[0015] this make it to only have when this shopping cart be just can again disengage token when being positioned at a bleeding point and correctly being pushed another shopping cart.

[0016] this bleeding point must so be configured, so that the information that this sensor receives when coming information that the sensor of first shopping cart of a series of shopping carts front receives and being equivalent to that this shopping cart pushed another shopping cart.

[0017] this has just prevented that the shopping cart that has pushed mutually from " the chaotic arrangement " being provided outside the bleeding point that provides according to this plan.

[0018] at this bleeding point, these shopping carts are braked by this retainer, and form the separately shopping cart group of brake of a difference.

[0019] in a development of the present invention, the arrangement that provides makes an authorized personage utilize a kind of special device and needn't use a token, the retainer of just can stop using or many shopping carts.

[0020] for example, if when the attendant will shift shopping cart onto another bleeding point from a bleeding point, necessity that Here it is.

[0021] if one piece of token is injected in last shopping cart, the retainer of this shopping cart is deactivated and this shopping cart can move.

[0022] so, this shopping cart is available for the general purpose that transport point is bought goods.

[0023] if attempt shopping cart is shifted onto outside the adimission area that is limited by this shopping cart supplier, then this retainer just is activated.

[0024] can not discharge token in this case.

[0025] Fig. 1 shows the present invention with an indicative icon:

[0026] many shopping carts are parked into a pile 1.Each shopping cart all is useful on and keeps and atoken element 2 of release token and aretainer 3 that at least a wheel is worked.Theseretainers 3 functionally are connected with thiselement 2.

[0027] key of release token is inserted in the token element 2.When discharging token,retainer 3 is activated.

[0028] in fact last shopping cart is pushed in this heap 1.In thistoken element 2a a token is arranged, this retainer 3a is not activated, and shopping cart can normally move.

[0029] this token element also can comprise a sensor, only has when being pushed into this shopping cart among the shopping cart of front fully, and this sensor just discharges token.

Industrial applicibility

[0030] the present invention can be applied in based on token provides shopping cart and it will be returned a bleeding point Anywhere.
